Identificación rápida de microorganismos en líquidos estériles con MALDI-TOF MS

Las nuevas tecnologías para diagnóstico microbiológico rápido y eficaz incluyen a la espectrometría de masas, la cual ha demostrado identificación rápida de microorganismos de colonias aisladas y frascos de hemocultivo. El objetivo del presente estudio es evaluar la capacidad y rapidez de la espectrometría de masas para el diagnóstico microbiológico de líquidos estériles

Histoplasma capsulatum in the bone marrow of an HIV-infected patient

A 41-year-old man was admitted to the emergency department with a 1-month history of weight loss, intermittent fever, and malaise. Generalized pallor, mild dehydration, and a temperature of 37.5 �C were found on physical examination. Initial blood workup revealed pancytopenia, elevated lactate dehydrogenase, and hypoalbuminemia. A fourth-generation HIV ELISA test was positive. His HIV-1 RNA viral load was 13 800 copies/ml and the CD4+ T-cell count was 3 cells/mm3 . Urine, blood, and cerebrospinal fluid cultures were without microbiological isolatio

Septic Pulmonary Emboli and Renal Abscess Caused by Staphylococcus aureus in an HIV-Infected Patient

Staphylococcus aureus is a common cause of bacteremia in the general population and can lead to serious metastatic infection particularly in immunocompromised persons. However, prompt diagnosis and management can result in favorable outcomes. In the following case report, the clinical course of an HIV-infected man is presented; he developed bloodstream infection (BSI) and associated complications: septic pulmonary embolism, right renal abscess, and ipsilateral renal vein thrombosis. Methicillin-resistant Staphylococcus aureus (MRSA) was identified as the cause of sepsis and successfully treated with surgery and antimicrobials. Intravenous vancomycin was the primary therapy, followed by oral linezolid after resolution of bacteremia
